Ok i'm finally home for Christmas now and i have time to integrate my barely used rel q200 into my setup: b&w 603 s3 fronts, b&w 601 s3 rears, sony str db1070 amp, lcr600 centre speaker. There's still one tihng i'm not sure about. I'm using the dual phono cable. There are 5 main settings i need to get right. these are: 1. The adjustible LFE high cut on the amp. Set at 120 STD at the moment. Should this be set to 75-80hz? 2. The high cut on the subwoofer itself. Set to around half way at the moment. P.S what is the difference between people saying 'high cut' and 'crossover'??? 3. The 3rd setting that i forgot about is the sub VOLUME. 4. I have all my speakers set to large and i always will for convenience sake. It makes it similar. (so bear this in mind). So therefore, what should the DB be set as on the amp. there is just one adjustable setting for this and it's called 'subwoofer +0db'. You can adjust it from -10 to +10 db. 5. The phase switch is set on 1 at the moment. Obviously 2 may suit different set ups. But i don't know yet without knowing what to set the other componant parts at. Bassicly i want a decent combination of the above settings which work in harmony with eachother. Which won't have to be continually altered and will suit both music and HT well. I'm not interested in perfection, but just a decent integration. My room is 4x4 metre by the way. I've looked in other threads, but my questions aren't answered all that clearly. So i started here from scratch, detailing my exact setup. I know it's a big ask, but could people try and advise me on a balanced setup taking all the above into account? Thank you so much if you can.
